Abstract:

In a first mode, a monitoring system inputs humidified gas through at least a portion of a conduit. At least a portion of the water in the humidified gas adheres to the inner surface of the conduit, inhibiting contaminants in the gas sample from adhering to the inner surface. The water in the humidified gas may also push any contaminants adhered to the surface of the sample line back out the sample line. In a second mode, after previously passing the humidified gas through the conduit, the monitoring system controls a flow of a gas sample including the contaminants through the conduit to a gas analyzer. The one or more layer of water on the inner surface of the conduit prevents or reduces a buildup of undesirable contaminants on an inner surface of a conduit that conveys gas samples.
